Whitehouse’s fascination with religion goes back to his own groundbreaking field study of traditional beliefs in Papua New Guinea in the 1980s. He developed a theory of religion based on the power of rituals to create social bonds and group identity. He saw that difficult rituals, like traumatic initiation rites, were often unforgettable and had the effect of fusing an individual’s identity with the group. Over the years Whitehouse’s theory of religiosity has sparked considerable debate and spawned several international conferences. [...]
When we can see how frequently certain kinds of rituals were performed, we think it’s possible to estimate—based on animal remains, for example—how often feasting events occurred. Some rituals involved killing large and dangerous animals. It’s been estimated that meat from a wild bull could feed 1,000 people. We can learn from burials, particularly in houses where burials are associated with founding events or closures. We can then estimate the frequency of particular rituals. The frequency of a ritual will be inversely proportional to the level of arousal it induces. Those inducers include sensory pageantry, singing, dancing, music, altered states of consciousness, and painful or traumatic procedures. We find that religions with high-frequency rituals will be more hierarchical than traditions that lack those rituals. [...]
Again, it really depends on what we mean by “religion.” I think the best way to answer that question is to try and figure out which cognitive capacities came first. We know that tool-use goes back deep in history. Homo habilis, otherwise known as handyman, is an early species that used tools, so it’s quite possible that he had some notion of creator beings. Language clearly plays an important role in some aspects of religion, like the development of a doctrinal system. But I’m not sure it’s necessary for many of the fundamental beliefs that undergird what we think of as religion. [...]
It may be a product of cultural evolution and the shift to much larger and more complex societies. When you use the singular “God,” you’re talking about some kind of high god, which probably means a god that’s omniscient and cares about the morality of our behavior and punishes us when we behave badly. That’s a relatively recent cultural innovation that may have been an adaptation to living in very large societies. [...]
That’s true, but the question is how we go about looking for meaning in the world. I personally don’t agree with the idea that the main explanation for religion is that we’re on a quest for meaning. I think we need to look at what participation in a particular cultural tradition—religious or otherwise—does for the individual and the community. There are lots of different components to religion. But if we’re just thinking about the ones that are universal, that seem to be part of our evolved psychology, I don’t think innate curiosity and desire to puzzle together the meaning of life explains religion.
